Collection Method: clinical testing

The c.343A>G (p.K115E) alteration is located in exon 2 (coding exon 1) of the PIRT gene. This alteration results from a A to G substitution at nucleotide position 343, causing the lysine (K) at amino acid position 115 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
